Abstract

Stomata of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) leaves failed to open in the light and close in the dark or respond to changes in the CO(2) concentration of the atmosphere in either light or dark when the leaves were in an O(2)-free atmosphere. In contrast, the expected responses to environmental changes were found in atmospheres containing 1.5% O(2). It appears that O(2) is necessary for both opening and closing of wheat and barley stomata.
